How Does Energy in an Inductor Change When Disconnected?
The energy stored in an inductor can affect a circuit in various ways. When the current through an inductor changes, the energy stored in the magnetic field also changes, causing a voltage to be induced in the circuit. This can lead to effects such as voltage spikes or a delay in the response of the circuit to changing currents.
